When you only want to make a fraction of a recipe, say like 1/2, you multiply that fraction by every measurement of an ingredient.
So, if a recipe calls for 2 cups of flour, you multiply the measurement of that ingredient by the fraction. In our case 1/2.
2 * 1/2 = 2/2 = 1
Now we need to only put 1 cup of flour.
Same difference with the question above. Raheim only wants 3/4 of the recipe. So, we multiply 3/4 by the measurement of every ingredient.
One of the ingredients is butter. In the original recipe, it is 2/3 of a cup.
Now we multiply 2/3 by 3/4.
2/3 * 3/4 = 6/12
Simplify the fraction.
6/12 = 1/2
So, Raheim should use 1/2 of a cup of butter.
